Can you share a bit more debug logging? Also what does the output of " docker inspect " name say?

This is the only message in the log. Do i have to activate debug logging?

[boehser-enkel]

I am also getting this right now for more container. These are on another pi. I just recently installed docker and dockerproxy there.

[boehser-enkel]

Debug Log: Seems normale and then it just says removing sensor and no container set up?

Can anybody show me the output of the following command: curl --unix-socket /var/run/docker.sock http://localhost/containers/<containername>/json | jq ' .HostConfig.NetworkMode'

Please replace "" with your container name.

[boehser-enkel]

Here is the output for portainer_agent. But this error appears for all container on this (remote) machine on the same time and sporadically. So i don't think thats it's a problem with a container. Rather with the machine and or communication?

[boehser-enkel]

Any update on this? Same error even with the newest version (of everything)

[ualex73]

This issue still persists?

[ualex73]

I will close this one, if it happens again, please raise a new issue.
